This is due to gcc-4.3 bug #476460. You can workaround it by a) not
using -funroll-loops on arm/armel b) using gcc-4.2 on arm/armel. We'll
soon have to consider changing the default gcc on armen back to gcc-4.2.

While ICEing compiler is really bad, I do wonder if unrolling loops
does anything good arm cpus, which typically have less 32K of
instruction cache..
